Background
Programmed cell death 1 ligand 2 (PD-L2 or PDCD1 ligand 2) is also known as Butyrophilin B7-DC, CD antigen CD273, which belongs to the immunoglobulin superfamily or BTN/MOG family. The expression of PD-L2 is up-regulated by IFNG/IFN-gamma stimulation in monocytes and induced on dendritic cells grown from peripheral blood mononuclear cells with CSF2 and IL-4. PD-L2 Involved in the costimulatory signal, essential for T-cell proliferation and IFNG production in a PDCD1-independent manner. PD-L2 interaction with PDCD1 inhibits T-cell proliferation by blocking cell cycle progression and cytokine production.

Source
Biotinylated Human PD-L2, Fc,Avitag (PD2-H82F6) is expressed from human 293 cells (HEK293). It contains AA Leu 20 - Pro 219 (Accession # Q9BQ51-1).
Predicted N-terminus: Leu 20

Molecular Characterization
This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag (Avitag™).
The protein has a calculated MW of 51.0 kDa. The protein migrates as 66-91 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Biotinylation
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

Biotin:Protein Ratio
The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

Endotoxin
Less than 1.0 EU per μg by the LAL method.

Purity
>95% as determined by reduced SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

Reconstitution
Reconstitute at 200 μg/mL in sterile deionized water. For best performance, we strongly recommend you to follow the reconstitution protocol provided in the COA.

Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower. Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at: 4-8°C for 12 months in lyophilized state; -70°C for 3 months under sterile conditions after reconstitution.

Bioactivity-ELISA
Immobilized Human PD-1, Fc Tag (Cat. No. PD1-H5257) at 2 μg/mL (100 μL/well) can bind Biotinylated Human PD-L2, Fc,Avitag (Cat. No. PD2-H82F6) with a linear range of 0.5-16 ng/mL (QC tested).
